  • Title: Predictive ability of creatinine clearance estimate models in pediatric bone marrow transplant patients.
    Author: Jacobson P, West N, Hutchinson RJ.
    Journal: Bone Marrow Transplant; 1997 Mar; 19(5):481-5. PubMed ID: 9052915.
    Abstract:
    The predictive performance of estimating creatinine clearance (CrCl) with pediatric clearance models was evaluated. Thirty-two pediatric patients with stable renal function between the ages of 1 and 14 years about to undergo bone marrow transplantation (BMT) who had 12-24 h urine collections for measurement of CrCl were studied. The measured CrCl was compared to CrCls calculated from seven models used to estimate CrCl in the pediatric population. The models used were Traub and Johnson, Schwartz et al, Counahan et al, modified Counahan et al, Ghazali and Barratt, Shull et al and Dechaux et al. Coefficients of determination (r2) between measured and estimated CrCls from models 1 to 7 were 0.47, 0.47, 0.47, 0.49, 0.47, 0.52, 0.47. The mean absolute percent errors for the models were 23.2-45.2%. In the majority of children, models overestimated CrCl. The tested models did not accurately predict CrCl and did not provide a reliable alternative to measured CrCl.
